Abstract

The invention relates to a self-locking assembling device for a spindle motor rotor. The self-locking assembling device comprises a spindle, a sleeve, the motor rotor, cylindrical surfaces and a threaded section. The motor rotor is mounted on the sleeve in an interference fit mode. The smooth cylindrical surface at the front end of the sleeve is connected with the smooth cylindrical surface at the front end of the spindle in a matched mode, and the threaded conical surface at the rear end of the sleeve is connected with the threaded conical surface at the rear end of the spindle. The guiding and positioning function of a motor and the spindle is achieved through the cylindrical surfaces, it is guaranteed that the spindle, the sleeve and the spindle motor are coaxial, and through the reasonable design of the conical surface thread rotating direction, it can be guaranteed that the motor rotor and the spindle are automatically locked in the rotating process. The sleeve is connected with the spindle through threads, and therefore undamaged assembly and disassembly of the motor and the spindle are facilitated, and the manufacturing cost and the maintenance cost are lowered.

Description

A kind of spindle motor rotor self-locking type assembling device
Technical field
The present invention relates to the assembly connection technology of a kind of electric spindle motor rotor and main shaft, belong to mechanical design field.
Background technology
Machine tool chief axis and motor combine together by electro spindle, are widely used in high-speed precise machine tool field.Electro spindle, by built-in motor Direct driver, achieves the Zero-drive Chain of main shaft.Due to needs High Rotation Speed or transmitting large torque, and with often dismounting, connection and the mounting technology of rotor and main shaft receive much concern, and method conventional at present comprises: be 1. press-fitted method: adopted by rotor on pressure force fit spindle rotor fitting surface; 2. cementing method: rotor and spindle rotor faying face are coated with gluing, and hot setting assembles; 3. hydraulic sleeve method: adopt hydraulic sleeve to be connected with main shaft interference by rotor, inject hydraulic oil again in hydraulic sleeve during dismounting, utilize pressure differential rotor slippage vertically to be unloaded.Should see, the problem that above a few class assembling mode is brought is dismounting difficulty, easily causes the damage of spindle motor rotor in unloading process simultaneously.
Summary of the invention
Technical problem: commonly use assembly connection method Problems existing for spindle motor rotor, the invention provides a kind of spindle motor rotor self-locking type assembling device, be intended to that acquisition one class formation is simple, convenient disassembly, transmitting torque reliable Novel main spindle motor assembly method.
Summary of the invention: for solving the problems of the technologies described above, the invention provides this device and comprises main shaft, and be located at the outerface of spindle and the sleeve coaxial with main shaft, be located at the rotor of sleeve outside, the left end of main shaft is the face of cylinder, and right-hand member is provided with thread segment; Wherein,
The front end of main shaft and hub internal bore adopts smooth, cylindrical peripheral surface to lead, and rear end is connected by thread segment;
Be threaded connection between sleeve and main shaft and realize self-locking.
Preferably, sleeve and main shaft adopt face of cylinder guide-localization and thread segment self-locking to be connected.
Beneficial effect:
Spindle motor rotor self-locking type assembling device of the present invention, adopts face of cylinder guiding positioning section, can realize the accurate location of rotor and main shaft, keep the dynamic balance accuracy of rotor; The employing section of being threaded, under the acting in conjunction of cutting (grinding) power and motor driving moment, can realize the self-locking of rotor; Be threaded and be easy to install, dismantle and safeguard.

Detailed description of the invention
Below in conjunction with drawings and the embodiments, patent of the present invention is described in further detail:
The present invention relates to a kind of spindle motor rotor self-locking type assembling device, comprise main shaft, sleeve, rotor, the face of cylinder and thread segment composition.Rotor interference is installed on sleeve; Sleeve and main shaft coupling part comprise front end smooth, cylindrical peripheral surface and to coordinate and the rear end threaded circular conical surface is connected, the face of cylinder realizes the guide-localization function of motor and main shaft, guarantee that main shaft, sleeve are coaxial with spindle motor, rational taper seat thread rotary orientation design can ensure in rotary course, to produce self-locking between rotor and main shaft.Adopt between sleeve with main shaft and be threaded, be easy to the harmless mounting or dismounting of motor and main shaft, reduce manufacture and maintenance cost.
See Fig. 1, spindle motor rotor self-locking type assembling device provided by the invention, this device comprises main shaft 1, be located at main shaft 1 outer surface and the sleeve 2 coaxial with main shaft 1, be located at the rotor 3 of sleeve 2 outside, the left end of main shaft 1 is the face of cylinder 4, and right-hand member is provided with thread segment 5; Wherein,
Rotor 3 is connected with sleeve 2 interference;
Main shaft 1 adopts smooth, cylindrical peripheral surface 4 to lead with the front end of sleeve 2 endoporus, and rear end is connected by thread segment 5;
The thread rotary orientation of sleeve 2 and main shaft 1 and main shaft work direction of rotation reasonable disposition, guarantee in main shaft rotary course, be threaded connection and realize self-locking between sleeve 2 and main shaft 1.
Sleeve 2 and main shaft 1 adopt the face of cylinder 4 guide-localization and thread segment 5 self-locking to be connected.
The above is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
